This 2010 movie is a remake of George A. Romero’s 1973 original.
Following the discovery of a military aircraft crash in a river in Ogden Marsh, Iowa, residents begin acting strange – including a farmer who locks his family inside a farmhouse and burns it down.
It’s discovered that a toxic virus, a biological weapon called Trixie, was on board the plane and on its way to Texas for destruction.
After the plane crashed, the virus leaked into the farming town’s water supply.
